Bullying takes place in every school and playground in our country. But what some parents see as a typical challenge of growing up is becoming more serious than ever before.

On April 6, 2009, 11-year-old Carl Walker-Hoover's family says he hanged himself after enduring bullying. Just 10 days later, 11-year-old Jaheem Herrera, another victim of bullying, took his own life, according to his family.

Carl's and Jaheem's mothers are speaking out in hopes that what they say happened to their sons will never happen to another child. "Today begins a national conversation on bullying," Oprah says.
